Argentina's Sebastian "Iron" Lujan is not the kind of boxer to hold a grudge. The tough Argentine brawler is training at the Otomi Ceremonial Center of Temoaya, Mexico - and he's working side by side with former opponent Antonio "The Tijuana Tornado" Margarito. Margarito and Lujan fought in 2005, with the Mexican slugger securing a tenth round stoppage.  In one of the more infamous injuries in the ring, the fight was stopped when Lujan's ear was nearly beaten off his head from Margarito's hard punches. The ear was partially hanging off and required several months of rehab to fully heal. 

Both boxers are preparing for their commitments on December 3rd at Madison Square Garden in New York City. Both fights will be carried by HBO pay-per-view.

Luján (38-5-2-1, 24 KOs) will face undefeated American Mike Jones (25-0, 19 KOs) in a welterweight world title eliminator. The winner will secure a shot at IBF champion Andre Berto. Meanwhile, Margarito (38-7-0-1, 27 KOs) will face Miguel Cotto (36-2, 29 KOs) in the main event for the WBA's junior middleweight title. Margarito stopped Cotto in the eleventh round of their initial 2008 meeting.
